Application filed December 27, 1919. Serial No. 347,711.

To aZZw/wm it mWccnrwni 7 Be it known that "I, FRENK SOWINSKY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Tie-Plate, of which the following is a specification.

The device forming the subject matter of this application is a tie plate, and one object of the invention is so to construct the plate that it may be attached securely to a tie, thereby to prevent accidental separation of the plate from the tie.

Another object of the invention is to provide novelmeans for locking the spike to the tie plate, so that the spike will not work loose.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in top plan, a portion of a tie whereunto the device forming the subject matter of this application has been mounted; Fig. 2 is a cross section taken approximately on the line 22 of Fig. 1; Fig. 3 is a top plan showing a portion of the tie plate, the spike appearing in section; Fig.4 is a fragmental perspective showing the head end of the spike; Fig. 5 is a section taken on the line 5-5 of Fig. 3; and Fig. 6 is a View similar to Fig. 5 but showing the relation of the parts after the spike has been driven to a seat.

In carrying out the invention there is provided a tie plate 1, made of metal, the said plate being adapted to be superposed on a tie 2. At its ends, the tie plate is supplied with depending wings 3, between which the tie 2 is located. Bolts or other securing devices 4 extend through the tie 2 and are engaged with the wings 3 at opposite sides of the tie. It will be obvious that the construction above alluded to affords a very secure means whereby the tie plate may be held upon the tie.

: fThetie plate I is provided with openings 5; Slits 6are formed in the plate 1 at the ends of the inner edge 7 of the opening 5. At the ends of the outer edge of the opening 5, diverging slits 8 are formed in the tie plate 1. The slits 6 and 8 form, in the tie plate 1, bendable tongues 9 extended along three sides of the opening 5;

In practice, and before the spike is driven,

the tongues 9 slant upwardly, as indicated at 10 in Fig. 5.

The invention includes a spike comprising a body 11 and a head 12, thehead 12 being of greater cross sectional area than the body, so that the head, on three sides of the spike project outwardly beyond the body. The head of the spike is connected with the body thereof by a reduced neck 14, defining a groove 15 extended around three sides of the spike. The head 12 of the spike is laterally extended as shown at 16, to engage with the base flange 19 of rail 18, in the well known manner. the sides of the head 12 of the spike, grooves or seats 17 are formed. these grooves being adapted to receive a claw bar or like tool, used to pull the spike.

When the spikes are driven, the inner edges of the spikes slide in contact with the inner edges 7 of the openings 5 in the tie plate 1. The overhanging laterally projecting head 12 of the spike engages the tongues 9, which are upwardly inclined, as shown at 10 in Fig. 5, and when driven forces the tongues downwardly and inwardly into the groove 15 of the spike, the tongues then being located in a common plane with the body, as shown at 20 in Fig. 6. It will be obvious that the tongues serve to lock the spike securely to the tie plate 1, the tie plate being held on the tie by the bolts 4:. Assuming that, as is common, the projecting portions 16 of the spike heads engage the flange 19 of the rail '18, it will be clear that the rail will be so held on the tie plate and on the tie, that accidental detachment of the rail will be unlikely to occur.

The device forming the subject matter of this application affords a simple but efficient means whereby all of the disadvantages and dangers attendant upon loose spikes may be avoided.

Having thus described the invention, what is claimed is In a device of the class described, a plate having an opening, there being slits in the plate at the ends of the inner edge of the opening and at the ends of the outer edge of the opening, the slits forming bendable upwardly slanting tongues extended along three edges of the opening; and a spike in-- eluding a head, a body, and a reduced neck connecting the head and the body and defining a groove extended along three sides of the spike and adapted for the reception of the tongues, the fourth side of the spike being smooth for sliding engagement With the plate at the inner edge of the opening.

In testimony whereof that I claim the foregoing as my own, I have hereto aflixed 15 my signature in therpresence of two Witnesses.

FRENK SOWINSKY.
